Abstract:

SERDP project MR-1712 entitled Portable Electromagnetic Induction Sensor with Integrated Positioning is complete. This report contains the final design, engineering challenges, modeling advancements, data analysis, and results from Aberdeen Proving Ground tests which resulted from this project. The instrument developed under this project is call Pedemis PortablE Decoupled Electromagnetic Induction Sensor. The instrument was conceived of as a sensor which combined the advantages of both the larger cart mounted sensors and the smaller handheld sensors. Pedemis is transported by one or two people and has nine transmitters and nine triaxial receivers with the receiver array being physically decoupled from the transmitter array leading to deployment and operational flexibility. The controlling electronics of Pedemis are lighter and more efficient than prior advanced electromagnetic induction instruments. We applied the Orthonormalized Volume Magnetic Source method ONVMS technique and the Joint Diagonalization JD method to data acquired with Pedemis at Aberdeen proving ground. Aberdeen Proving Ground blind grid results are better than any previous results from any group and instrument at APG.
